Technical field
The present invention relates to a kind of Pneumatic vehicle tires with tyre surface, wherein the tyre surface has in radial outside arrangement
Tyre surface section, wherein the tyre surface section has material bands, and the material bands are approximatively in a circumferential direction with multi-circle spiral flow shape
Ground arrangement, wherein in the region of the tyre surface section, which has at least two on the longitudinal direction of the material bands
A layer, wherein the first layer is formed by the first rubber compound and the second layer is by being different from first rubber compound
Second rubber compound is formed, wherein the radially-outer surface of the tyre surface section is connected to the tire by the first layer and the second layer
In the inner radial surface of face section.The invention further relates to a kind of methods for producing such Pneumatic vehicle tire.
Background technique
There is different requirements to the tyre surface of Pneumatic vehicle tire.Since tyre surface is directly contacted with road, it is important that tyre surface
Radially-outer surface during entire use in adhere to, grab ground and braking ability in terms of have advantageous performance.In addition,
Good operating characteristics, low-rolling-resistance and low noise discharging are all advantageous.It is used under for riving condition in winter
Tire in the case where, it should be ensured that the advantageous property of snowfield operating aspect, dry operational, wet braking performance, cornering stiffness,
And rolling resistance.
Generally, the improvement that tyre surface makes all properties obtain equal extent can not be implemented in these aspects of performance.
Known such tire, tread surface have the multiple regions including different rubber compounds.
Therefore, 11 2,006 004 011 T5 of DE discloses a kind of tire, which has the tire in radial outside arrangement
Face region, the tread area are formed by the material bands of two layers with different rubber compounds, wherein a kind of compound
With conductive design and another compound does not have conductive design.Here, in the axial centre of the tyre surface, material strips
The volume ratio ratio of conductive compound in band is smaller in shoulder zone.Such tyre surface is the multilayer squeezed out by winding
Material bands produce.In the case where having the shorter production cycle, such tire is considered to have small rolling
Dynamic resistance and ability for eliminating electrostatic charge.
A kind of tire of the type described in introductory song known from 0 875 367 A2 of EP.Here, tyre surface section is in tyre surface
Extend on entire axial width, and the rubber compound of the two layers of material bands is different in hardness.By having not
This combination of the rubber compound of same hardness, the tire should have advantageous adhesion while being readily produced.So
And the tyre surface with the different region of hardness is special with unfavorable noise emission due to the difference in the rigidity in these regions
Sign and unfavorable uneven wear.
Summary of the invention
General object of the present invention is to provide a kind of Pneumatic vehicle tire, which has during the driving period
Lower noise emission and more evenly abrasion and at least one goal conflict between two other performances in terms of obtain
It improves.In addition, the tire should be readily produced.
According to the present invention, the purpose is by the fact that realize: under sulfided state, first rubber compound and this
Two rubber compounds have approximately uniform Xiao A hardness, are determined at room temperature according to DIN ISO 7619-1, and vulcanizing
